Method for generating biogas by using device for promoting uniform distribution of strain of multi-region circular fermentation system

Abstract

The invention discloses a method for generating biogas by using a device for promoting uniform distribution of a strain of a multi-region circular fermentation system. The method comprises the following steps: pouring a fermentation raw material into a feed pipe; pushing a biogas slurry to flow to adjacent fermentation zones when biogas is generated in the fermentation zones formed between side walls of feed/discharge pipes and gas baffle plates or the fermentation zones formed between adjacent gas baffle plates in a circular fermentation pipeline, and pushing the biogas slurry into the feed pipe, the discharge pipe and a bacterium distributing device; when the fermentation zones are full of biogas, flowing the biogas continuously generated by fermentation to the adjacent fermentation zones which are not full of biogas until all the fermentation zones are communicated with one another; and when the biogas slurry liquid level in the circular fermentation pipeline reaches the lowest position of the side wall of the feed pipe or the discharge pipe, overflowing the biogas continuously generated by fermentation out of the fermentation system and discharging the biogas to the atmosphere.

Description

technical field [0001] The invention relates to a novel energy generating device, in particular to a fermentation system in the technical field of biogas. Background technique [0002] The hydraulic biogas digester type has the following advantages: (1) The structure of the pool body has good mechanical performance, and makes full use of the bearing capacity of the soil, so it saves labor and materials, and the cost is relatively low; (2) It is suitable for filling a variety of fermentation Raw materials, especially a large amount of crop stalks, are very beneficial to the accumulation of manure in rural areas; (3) To facilitate frequent feeding, toilets and pig pens can be built on the biogas digester, and feces can be cleaned into the pond at any time; (4) Surrounding the biogas digester Contact with the soil has a certain effect on the heat preservation of the pool body. [0003] Since there is no stirring device in the hydraulic biogas digester, the scum in the tank is ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the traditional biogas fermentation system has a short fermentation route, and the poor fluidity of the biogas slurry leads to uneven separation of strains and easy crusting, and incomplete fermentation of fermentation materials, etc.
